Title: Cycloidal mass spectrometer
Inventor: VOSS GUENTER F
IPC: H01J7/24
Filed: 2003-02-20
Granted: 2011-04-26
Abstract: A circular cycloidal mass spectrometer, Fig. 5, has an outer electrode (74) of generally circular configuration and an inner electrode (70) having generally circular outer periphery with an annulus (76) for the flow of ions (90) defined therebetween. The electrodes (70, 74) are structured to create an electric field therebetween. A magnetic field generator is structured to create a magnetic field oriented generally perpendicular to said electric field. An ion beam source (80) for injecting ions (82) into the annulus (76) for travel therearound is provided, and an ion exit (100) for discharge of the ions traveling in said annulus is provided with an ion collector (102) being disposed adjacent to the ion exit (100). The circular cycloidal mass spectrometer may be structured to provide, under the influence of the electric field and magnetic field, a path of travel (90, 92, 94, 96) for the ion beams, which is similar to either epicycloidal or hypocycloidal curves. If desired, elliptical shapes or other suitable shapes providing a nonlinear path of ion travel may be employed. A filter may be interposed between said outer electrode and said inner electrode.

Abstract: L'invention concerne un dispositif et un procédé servant à rectifier une bande de matière souple (1) qui est conduite vers la machine de traitement et dont la face inférieure est orientée de manière incorrecte vers le haut. Cette erreur est due à une torsion ou au raccord incorrect de deux extrémités de bande de matière. On effectue pour la rectification au moins une rotation de la bande de matière (1) autour de son axe longitudinal afin que la face inférieure de la bande de matière soit à nouveau orientée vers le bas de manière correcte et que la véritable face supérieure de la bande de matière parvienne à la machine de traitement. L'invention vise à rectifier la bande de matière souple conduite de manière incorrecte à la machine de traitement et à réduire l'apparition de déchets en matière semi-finie ainsi que des périodes d'arrêt de la machine de traitement. A cet effet, une paire de cylindres rotative (2) exécute une rotation correctrice de la bande de matière (1) autour de l'axe longitudinal de cette dernière de sorte que la face inférieure de la bande de matière est à nouveau orientée de manière correcte vers le bas.

Abstract: To manage the transmission of information packets on channels of a telecommunications network, the packets are organised into user queues received in respective buffers, measuring the occupancy level of the buffers. The users are sorted into respective classes (RT, NRT) identified by the service mode requested. After determining the propagation conditions on the transmission channel respectively associated to said users, the priority in the transmission of the packets is determined, choosing the order in which the respective queues are visited as a function of: - a first level priority, linked to whether the users belong to the respective classes of service (RT, NRT), - a second level priority, linked to at least a parameter chosen between the level of occupancy of the respective buffer and the propagation conditions of the respective channel.

Title: Power tool lockdown device
Inventor: ANDERSON GARY
IPC: E05B65/00
Filed: 2005-05-10
Granted: 2012-11-20
Abstract: A lockdown device for a power tool includes a housing containing a battery, a processor, and a relay. The housing mounts to an aperture in a power tool so as to be locked thereto and so as to be immovable therefrom without dismantling of the power tool. An electrical power cord mounts to the housing in electrical communication with the processor and relay. The processor communicates with the relay for selectively electrically opening and closing the relay upon instructions from the processor. The processor detects a mains electrical power supply and sequences opening of the relay following a pre-set delay upon detection by the processor of an absence of, or loss of the mains electrical supply to the processor and the relay. A removable key cooperates with the processor and relay for the manual closing of the relay to power the power tool.

Abstract: In a turbo coder, rate conversion and/or rate matching is achieved by deleting parity bits P1 and P2 from the outputs of two constituent coders, one supplied with data bits to be coded and the other supplied with the same data bits after interleaving. Deleted bits are determined by a rate matching control unit directly for the P1 bits and via a similar position interleaving step for the P2 bits. A similar rate matching arrangement is provided for only two of the three outputs of a rate 1/3 convolutional coder, the third output corresponding to a strongest coding polynomial in terms of minimum free distance and none of its coded data bits being deleted.
